SCALEBEAM.

Application filed June 5,

Z '0 all whom it may concern:

Be it known that I, GEORGE W. LANMAN, a citizen of the United States,residing at Texas City, in the county of Galveston and State of Texas,have invented new and useful Improvements in Scalebeams, of which thefollowing is a specification.

In the ordinary construction of beam scales, the beam, under the weightof the load thereon, is liable to tilt or cant so that there is africtional engagement between he hangers and the beam, and as aconsequence, the weighing by the scale is not at all times accurate. Itmay, therefore, be considered the primary object of this invention toconstruct a beam scale in such a manner that no friction will beoccasioned between the stirrup hangers and the beam of the scale whenthe beam is arranged in counter-balancing position with respect to theweight thereon.

To the attainment of the above broadly stated objects and others whichwill appear as the nature of the invention is better un derstood,reference is to be had to the drawings which accompany and form part ofthis application.

In the drawings Figure 1 is a side elevation of a beam scale providedwith the improvement.

Figure 2 is a fragmentary elevation to illustrate the arrangement of thebeam when the beam is canted to receive a load.

Figure 3 is a similar view but showing the beam in a horizontalposition, as when the weight has been adiusted to counter-balance theweight of the load on the beam.

Figure t is a sectional view on the line L -a of Figure 3.

In Figure 1 of the drawings, I have illustrated the improvement inconnection with a cotton weighing beam scale, but, of course, it is tobe stated that the invention is susceptible to application upon othertypes of beam scales.

The beam of the scale is indicated by the numeral 1. The hanger thatsupports the beam on the frame of the scale is indicated by the numeral2 and the hanger to which the load to be weighed is attached, is indi-1925. Serial No. 35,188.

cated by the numeral 3. Both of the hangers are of similar constructionexcept that the same are reversely arranged.

The upper edge of the beam, at the portions thereof over which the armsof the U-shaped hangers are arranged, 1s w1dened,'as at 4. Thepearshaped trunnions for the stirrups are both indicated by the numerals5, and each of the hangers has its shaped openings 6 trunnions. This, ofcourse,

The lugs 8 are slightly received in these depressions. The lugs clinedwalls provided 1 central between the will hold the beam hangers when thebeam load thereon, as disclo drawings. The lugs traveling on the inbythe depresslons is tilted to receive a sed in Figure 20f the arearranged opposite the center and therefore the deeper portions of thedepressions beam balances the disclosed in Figures 3 Thus there is notween the sides of the when the weight on the load carried thereby, as

frictional engagement behangers and the beam with the result that theload on the beam can be accurately weighed.

The simplicity and vention will advantages of the inbe readily apparentto those skilled in the art to which such inventions relate, andtherefore a further detailed description is not believed necessary.

Having 1. A beam scale having described the inventlon,

I claim hangers for supporting the beam and for supporting the loadcarried by the beam,

ers having pear-shape shaped trunnions on each of said hangd eyes toreceive pearthe sides of the beam and thee-aid hangers having fingerseXtending beyond the eyes,

each of said fingers having. an inwardly directed lug and the sides ofthe beam being formed with depressions disposed directly opposite saidlugs.

2. A beam scale having hangers for supporting the beam and forsupporting the load carried by the beam, each of said hangers havingpear-shaped eyes to receive pearshaped trunnions on the sides of thebeam and the said hangers having fingers extending beyond the eyes, eachof said fingers 10 having an inwardly directed lug and the sides of thebeam being formed with depressions disposed directly opposite said lugs,and said depressions having their Walls beveled inwardly to the centerthereof. 15 In testimony whereof I afiix my signature.

GEORGE V. LANMAN.
